QUNTED STATI-521% inentsin Collapsible Beds, of which the following-.is a specification.

:This invention relatesl to improvements in and has as its principal object, the provision of an, article of furniture-which may be extended both longitiidinally andlaterally so as to afford' a hed, suitable for onev or more persons, as maybe4 preferred. or collapsed into relatively small `compass;resembling an ordinary chest.

A. further object is to provide such article with means manually manipulated from the end thereof, whereby lthe structure may be extended lengthwise and in addition thereto, extended sidewisc as well, and finally, to provide an article of the class described which is capable of containingr the several articles used in connection with a bed, a's springs, mattress blankets, pillows, and the like, when in a 'olded or collapsed position, the saine being readily portable from place to place as mauiT be desired.

These and other Vlike objects are attained by the novel design, construction and conibination of parts hereafter described and shown in the accompanying drawings, forniing a materialpart of the specification, and in which Figure 1 is a top plan view of the structure shown in an extended position, the n'n\t.

trcss and bedding being removed.

Fig. 2 is a partial sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a transif'erse sectional view taken on line 3-8 of Fig. 1.

Fig'. 4 is a front elevation showing' the article in a folded l'iosition. and

Fig. 5 is an end View of the plates un folded.

The device comprises a pair of oppositcly disposed side platesl 10, to the front corners of which are connected, by hinges 11, a pair 'of doors 12 adapted to fold inwardly7 when the device is in a collapsed position as indi cated in Fig. ll.

teeth 16 and 1'( of which engage iipftrop-y pos-ite sides of the pinions 18j and A19, ariranged upon stems' 2O andQI, onV whchfaite' secured bevel pinions Q2 'and "23 meshing with mating piniolis :2l and 25, liiuntd npon `a transverse shaft 26, carxiedf'iiiliealn ings 2T, supported' by the plate 13, 'iin'tii'rn'f fixed between the upper-parts of the stav "libV tionary back and fi'lont plates,respectively? shaft B0 provided with acle'ivisjoint251ienn gagingnthe shaft whiclrextends out-'-l .48 and 4S the bearings having `betweenf wardly beyond the end plate 10. `iivhcre it furnished with a crank 33.

In addition to the racks 1-l and l5, snpporting bars 35 are rigidly attached to the extreme upper front corner of the end plates adjacent to the hinges 1l, the bars 35j heilig telescopically receivable within a fixed tube 3G which extends longitndina'll`5v at the npper front edge of the article.

From the 'foregoing it will be understood that when the crank 33 is turned. causing;r the pinions 18 andll) to rotate. that the rack bars ll and 15 arenlovcd in opposite direc tions. in such manner as to carry the plates 1t) outwardly, thus extending:` the article lengthwise. or bring thorn inwardlv toward a common center.

At thc extreme front of the doors 1:2 are connected .similar rods 3h having downtnrned ends 50. formed in the manner of a hook and engageable with clips 10, secured to the inner front edge of the doors l2, the opposite ends of the rods 3S being telesco icall;v received within a tube 2, in turn E ing engaged by transverse rods l-l slidably held within tubes 45, secured to tlieflongitndinal tubes 3G, at one end, and to the. fixed .bach 45 of the. article at the other end, it

plate 62 extends below the l the article between the back-p 'te' 48, to the upper edge of which is attacied by means o hinges 64, a cover plete (S5, adapted` to overlie the structure Lwhen in a closed position.' From the foregoing, it wilL. be seen that is provided which lengthwise to form a `couch and 'extended sidewise so that the 'couch may be used for more than one perthe various beddin material bein disosahle within when t e article is olded into its smallest compass.

4of said end elements,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isz-- In a collapsible bed, the combination with a frame work having movable end elements, pairs of rack bars attached to the inner side a pinion operatively engaged with each of said pairs of rect bars,l1ncans for transmitting rotary motion to said pinions, tubular guides for said end elements, 'said tubular guides being a coinponent part of the frame, leaves hinged to the vertical front edge of said end elements, said leaves bein foldable toward each other or extend to form a bed support,` rods for holding said end elements when in an extended open position, said rods being telescopically -engaged one with another, and means for moving said side elements laterally to or f m said frame.
